What 5.7 round did you test? There's a huge difference in AP capabilities between the various 5.7 rounds. I've personally witnessed a Level II vest stop 197SR on the last two layers, whereas SS192 zipped through 48 layers of the same vest (vest folded over onto fresh patches). And that's not even getting into the rounds that are actually purposed to penetrate body armor (this vest was also shot with various legacy rounds and performed to NIJ specs, so it wasn't a junker). I also witnessed some ballistic tiles (not sure the name/material, something similar feeling to fiberglass) get shot with SS192 and 197SR...the 1/2" tile was supposedly rated up to .44 Mag and stopped 197SR, but 192 zipped right through the 9/16" tile. Not trying to start a 5.7 argument, just pointing out that even within the sporting rounds there's HUGE variations in the AP capability, so it's important to note which round was fired.
